It could be from a bad dream, but if this behavior increases in frequency I'd let the vet know about it, or at least mention it during her next appointment, if it continues.
Also, as she is a rescue, have you had the opportunity to have any bloodwork run on her? If yes, fine. If not, it may not hurt to have basic bloodwork done to make sure nothing medical is going on with her, and it would establish a baseline for comparison if she does have problems in the future. |
